In this photo, I did farming work with my friends in some village like 2 hours away from Seoul. This is not the organization WWOOF as i linked above. But for those, who want to experience the farming life in Korea, you could register as an member in WWOOF KOrea (They are international organization by the way, I did it once in Netherland as well)
I highly recommended this farming for those who want to experience more about Korea lifestyle, not only K-Pop, and K-drama things.
They also offered 1 days farming trip with the fee is 15000won, (15usd).
